Anti-Fascist Council for the National Liberation of Yugoslavia

Josip Broz Tito led the Yugoslav Partisans as a resistance to Axis occupation of Yugoslavia

The Kingdom of Yugoslavia acceded to the Tripartite Pact on 25 March 1941 under pressure from the Nazi Germany. The latter sought to protect its southern flank before the planned invasion of the Soviet Union, while ensuring the availability of transport routes and economic resources in the Balkans where the Greco-Italian War was in progress. In response to the pact, Royal Yugoslav Armed Forces generals staged a coup d'état deposing the government and Prince Regent Paul. Royal Yugoslav Air Force General Dušan Simović became the Prime Minister and the regency was abolished by declaring Peter II of Yugoslavia of age and thus the king even though he was only seventeen.[1]

On 6 April 1941, the Axis powers invaded and quickly occupied Yugoslavia. Parts of the country were annexed by its neighbours, and the Independent State of Croatia (NDH) was carved out as a Ustaše-ruled Axis puppet state. With the country's defeat imminent, the Communist Party of Yugoslavia (KPJ) instructed its 8,000 members to stockpile weapons in anticipation of armed resistance.[2] By the end of 1941, the armed resistance spread to all areas of the country except Macedonia.[3] Building experience in clandestine operation across the country, the KPJ proceeded to organise the Yugoslav Partisans[4] as resistance fighters led by Josip Broz Tito.[5] The KPJ believed that the German invasion of the Soviet Union had created favourable conditions for an uprising. The KPJ politburo founded the Supreme Headquarters of the National Liberation Army of Yugoslavia with Tito as commander-in-chief on 27 June 1941[6] and the Partisans waged war against the occupying powers until 1945.[7]d.

King Peter II and the government fled Yugoslavia in April 1941 when it became apparent the royal army would not be able to defend the country. The decision to abandon organised armed resistance put the Yugoslav government-in-exile in a weak position, further eroded by political differences between ministers.[8] The government, an extension of the post-coup government led by Simović, based its legitimacy on the 1931 Yugoslav Constitution, which made it responsible to the king.[9] It lost three Croatian Peasant Party (HSS) ministers including the party's leader and the deputy prime minister Vladko Maček, who resigned and stayed in the country. The HSS thus split and lost influence. Džafer Kulenović, the only minister drawn from the Yugoslav Muslim Organization, also resigned.[10]

The government-in-exile was split along an ethnic line separating the HSS from a bloc of Serb ministers drawn from several disunited parties.[9] The divisions deepened because the HSS ministers were reluctant to publicly discuss and condemn Ustaše atrocities against Serbs in late 1941. In January 1942, Simović was replaced by Slobodan Jovanović and his decision to support the Chetniks widened the rift with the HSS ministers.[11] Jovanović saw the Chetniks as a guerrilla force promising the restoration of the monarchy after the war. In combination with fear of communism, this led him to ignore information about Chetnik collaboration with the Axis powers,[12] and appoint their leader Draža Mihailović the Minister of the Army, Navy and Air Forces.[13] At the same time, the government promoted Mihailović to Army General and formally renamed the Chetniks the "Yugoslav Army in the Homeland".[14] In June 1943, Jovanović resigned, unable to reunite the ministers, and his replacement Miloš Trifunović also resigned after less than two months. In August, Božidar Purić was appointed the prime minister of a largely administrative government mostly composed of civil servants,[15] although Mihailović retained his ministerial position.[16]

After Italy defected to the Allies and Western Allied forces advanced towards Yugoslavia, Tito announced another session of the AVNOJ.[32] Since the previous session, the Western Allies began to support the Partisans,[33] and Tito considered a British landing in Yugoslavia likely.[34] In October 1943, just before the second session, the KPJ central committee established the National Committee for the Liberation of Yugoslavia (NKOJ), an all-Yugoslav executive body,[35] appointed to perform the role of an interim government.[36]

The AVNOJ reconvened in Jajce on 29 and 30 November 1943; Ribar chaired the meeting as president of the executive council. The KPJ originally planned for the second session of the AVNOJ to be attended by 250 delegates elected by regional land councils. The number of delegates was subsequently increased by 53 to include delegates from Macedonia and the Sandžak. In total, 78 delegates were to be elected in Croatia, 53 in Bosnia and Herzegovina, 53 in Serbia, 42 in Slovenia, 42 in Macedonia, 16 in Montenegro, 11 in Sandžak, and 8 in Vojvodina.[37] Of the planned 303, 142 delegates arrived by the start of the session and 163 deputy delegates also attended the session. No deputies from Sandžak or Macedonia were present. The Main National Liberation Committee for Serbia was unable to hold elections because of the German occupation of Serbia. Instead, the Serbian delegates were appointed by individual Partisan units originally from Serbia; as a result, eastern Yugoslavia was underrepresented.[38]

AVNOJ decision to build a new Yugoslavia as a federation to ensure equality of its nations

The AVNOJ made several decisions of the highest political and constitutional significance. It declared itself the supreme legislative body in the country and the representation of Yugoslav sovereignty;[39] affirmed a commitment to forming a democratic federation; and recognised the equal standing of Bosnia and Herzegovina, Croatia, Macedonia, Montenegro, Serbia and Slovenia in the future federation. Only Sandžak was listed with other lower-ranked regional entities, even though its land council was still included among the "seven basic bodies of people's government". Though the position of individual nations and regions were not further elaborated,[40] the second session of the AVNOJ determined the type of federal system to be introduced in Yugoslavia, modelling it on the Soviet Union.[41]

Tito's views prevailed over the model adopted by the State Anti-fascist Council for the National Liberation of Croatia and the Communist Party of Croatia (KPH),[41] a nominally independent part of the KPJ established in Croatia.[42] The KPH leader Andrija Hebrang advocated a loose Yugoslav federation where communist parties and bodies established in federal units would be sovereign. In contrast, Tito's vision for the federal units was as administrative divisions only. Hebrang was replaced in late 1944 by Vladimir Bakarić, who aligned the KPH's views on federalism to Tito's.[41]

The AVNOJ also denied the legitimacy of the Yugoslav government-in-exile and forbade the return of King Peter II to the country until its people could decide on the future of the monarchy after the war. It also declared all agreements previously concluded by the government-in-exile to be subject to review and approval, renegotiation or cancellation while declaring any further agreements concluded by the government-in-exile void. Furthermore, the AVNOJ declared that Yugoslavia had never accepted the 1941 partition.[39] Finally, Tito was awarded the rank of Marshal of Yugoslavia.[43]

The AVNOJ elected a new presidency consisting of sixty-three members, chaired by Ribar.[25] Five vice-presidents were appointed: Antun Augustinčić, Moša Pijade, Josip Rus, Dimitar Vlahov, and Marko Vujačić. Radonja Golubović and Rodoljub Čolaković were appointed secretaries of the presidency.[44] Some of the AVNOJ delegates were non-Communists so the presidency included some non-Communist members of the pre-war HSS and the Independent Democratic Party. The NKOJ was confirmed in the role of the government. Tito was appointed the president of the NKOJ and had three vice-presidents.[25] Two were KPJ members Edvard Kardelj and Vladislav S. Ribnikar, and the remaining one was Božidar Magovac of the HSS.[45] Finally, the AVNOJ formally praised and thanked Tito's Supreme Headquarters, and the Partisan forces for their armed struggle.[39]

On 15 January 1944, the AVNOJ introduced multilingualism to its proceedings, deciding to publish its official work in Serbian, Croatian, Slovene and Macedonian.[46][47] In February, the AVNOJ and the NKOJ adopted a new emblem of the future federation at Tito's request.[48][46] The emblem consisted of five lit torches burning as one flame representing five united nations; this was framed by sheaves, topped by a red five-pointed star, and crossed by a blue stripe bearing the name of the country, Democratic Federal Yugoslavia.[46]

Stalin was enraged by the AVNOJ's rejection of Soviet advice in its establishment of the NKOJ as an interim government and explicit repudiation of the government-in-exile. Stalin was specifically worried about Tito's assumption of the presidency of the NKOJ and his elevation to the rank of Marshal. He thought that this would signal to the Western Allies that the KPJ was actually fighting for a revolution. Stalin was further angered by the fact that he received no prior notice of the decisions.[43]

To Stalin's surprise, the Western Allies did not strongly oppose the AVNOJ's decisions. The flow of British equipment and arms to the Partisans, which had started in the second half of 1943 on the basis of the Churchill's Mediterranean strategy, continued.[49] Only days after the AVNOJ's second session, the Allies recognised the Partisans as an Allied force at the Tehran Conference, and cut off further aid to the Chetniks.[50] On British Prime Minister Winston Churchill's urging, the government-in-exile led by Ivan Šubašić and the Tito-led NKOJ signed the Treaty of Vis on 16 June 1944; the government-in-exile recognised the AVNOJ in return for the NKOJ's pledge to postpone the decision on the constitution of Yugoslavia until after the war.[51] Tito and Šubašić concluded another agreement on 1 November in Belgrade; Šubašić confirmed AVNOJ as Yugoslavia's legislative body and agreed to form a new 18-person government. Six of the members would come from the government-in-exile and twelve would be NKOJ members.[52] The second session of the AVNOJ also drew a response from the Chetnik leadership. At the Ba Congress held in January 1944, they proposed an alternative solution for the post-war government.[53] The congress also condemned the AVNOJ in line with the contemporary Chetnik propaganda as a product of collaboration of Communists and Ustaše against Serbs.[54]

On 21 November 1944, the presidency of the AVNOJ declared the Germans of Yugoslavia to be collectively guilty for the war and enemies of Yugoslavia. Germans in Partisan-controlled areas were interned. Prior to 1944, about half a million Germans lived in Yugoslavia. About 240,000 were evacuated before the arrival of the Red Army, another 150,000 were later deported to the USSR to work as forced labour, 50,000 died in Yugoslav-run labor camps and 15,000 were killed by the Partisans. Most of the others were expelled from Yugoslavia and German property was confiscated. By the time of 1948 census, fewer than 56,000 ethnic Germans remained.[55]
